4-6 months has been my experience over the last year.
That's what I was worried about. They are a little vague on their website. I saw a review where they were pretty disappointed by the time it took to receive the trigger. I guess I could order one now and expect it by Thanksgiving? Ha ha.. Took care of the problem though, just using one of my RRA 2 stage varmint match triggers... CMC single stage went into the Armalite AR10T.. Which is probably going up for sale soon.. Still debating that one though..
